In the Linux kernel, the following vulnerability has been resolved: tun: avoid double free in tun_free_netdev Avoid double free in tun_free_netdev() by moving the dev->tstats and tun->security allocs to a new ndo_init routine (tun_net_init()) that will be called by register_netdevice(). ndo_init is paired with the desctructor (tun_free_netdev()), so if there's an error in register_netdevice() the destructor will handle the frees.

In the Linux kernel, the following vulnerability has been resolved: phonet/pep: refuse to enable an unbound pipe This ioctl() implicitly assumed that the socket was already bound to a valid local socket name, i.e. Phonet object. If the socket was not bound, two separate problems would occur: 1) We'd send an pipe enablement request with an invalid source object. 2) Later socket calls could BUG on the socket unexpectedly being connected yet not bound to a valid object. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: phonet/pep: se niega a habilitar una tubería independiente. Este ioctl() supone implícitamente que el socket ya estaba vinculado a un nombre de socket local válido, es decir, objeto Phonet. • https://git.kernel.org/stable/c/0bbdd62ce9d44f3a22059b3d20a0df977d9f6d59 https://git.kernel.org/stable/c/b10c7d745615a092a50c2e03ce70446d2bec2aca https://git.kernel.org/stable/c/311601f114859d586d5ef8833d60d3aa23282161 https://git.kernel.org/stable/c/982b6ba1ce626ef87e5c29f26f2401897554f235 https://git.kernel.org/stable/c/48c76fc53582e7f13c1e0b11c916e503256c4d0b https://git.kernel.org/stable/c/52ad5da8e316fa11e3a50b3f089aa63e4089bf52 https://git.kernel.org/stable/c/53ccdc73eedaf0e922c45b569b797d2796fbaafa https://git.kernel.org/stable/c/75a2f31520095600f650597c0ac41f48b •

In the Linux kernel, the following vulnerability has been resolved: tomoyo: fix UAF write bug in tomoyo_write_control() Since tomoyo_write_control() updates head->write_buf when write() of long lines is requested, we need to fetch head->write_buf after head->io_sem is held. Otherwise, concurrent write() requests can cause use-after-free-write and double-free problems. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tomoyo: corrige el error de escritura UAF en tomoyo_write_control() Dado que tomoyo_write_control() actualiza head->write_buf cuando se solicita write() de líneas largas, necesitamos recuperar head->write_buf después head->io_sem se mantiene. De lo contrario, las solicitudes de escritura () simultáneas pueden causar problemas de use-after-free-write y de doble liberación. • https://git.kernel.org/stable/c/bd03a3e4c9a9df0c6b007045fa7fc8889111a478 https://git.kernel.org/stable/c/a23ac1788e2c828c097119e9a3178f0b7e503fee https://git.kernel.org/stable/c/7d930a4da17958f869ef679ee0e4a8729337affc https://git.kernel.org/stable/c/3bfe04c1273d30b866f4c7c238331ed3b08e5824 https://git.kernel.org/stable/c/2caa605079488da9601099fbda460cfc1702839f https://git.kernel.org/stable/c/6edefe1b6c29a9932f558a898968a9fcbeec5711 https://git.kernel.org/stable/c/2f03fc340cac9ea1dc63cbf8c93dd2eb0f227815 https://lists.debian.org/debian-lts-announce/2024/06/ •

In the Linux kernel, the following vulnerability has been resolved: dccp: fix dccp_v4_err()/dccp_v6_err() again dh->dccph_x is the 9th byte (offset 8) in "struct dccp_hdr", not in the "byte 7" as Jann claimed. We need to make sure the ICMP messages are big enough, using more standard ways (no more assumptions). syzbot reported: BUG: KMSAN: uninit-value in pskb_may_pull_reason include/linux/skbuff.h:2667 [inline] BUG: KMSAN: uninit-value in pskb_may_pull include/linux/skbuff.h:2681 [inline] BUG: KMSAN: uninit-value in dccp_v6_err+0x426/0x1aa0 net/dccp/ipv6.c:94 pskb_may_pull_reason include/linux/skbuff.h:2667 [inline] pskb_may_pull include/linux/skbuff.h:2681 [inline] dccp_v6_err+0x426/0x1aa0 net/dccp/ipv6.c:94 icmpv6_notify+0x4c7/0x880 net/ipv6/icmp.c:867 icmpv6_rcv+0x19d5/0x30d0 ip6_protocol_deliver_rcu+0xda6/0x2a60 net/ipv6/ip6_input.c:438 ip6_input_finish net/ipv6/ip6_input.c:483 [inline] NF_HOOK include/linux/netfilter.h:304 [inline] ip6_input+0x15d/0x430 net/ipv6/ip6_input.c:492 ip6_mc_input+0xa7e/0xc80 net/ipv6/ip6_input.c:586 dst_input include/net/dst.h:468 [inline] ip6_rcv_finish+0x5db/0x870 net/ipv6/ip6_input.c:79 NF_HOOK include/linux/netfilter.h:304 [inline] ipv6_rcv+0xda/0x390 net/ipv6/ip6_input.c:310 __netif_receive_skb_one_core net/core/dev.c:5523 [inline] __netif_receive_skb+0x1a6/0x5a0 net/core/dev.c:5637 netif_receive_skb_internal net/core/dev.c:5723 [inline] netif_receive_skb+0x58/0x660 net/core/dev.c:5782 tun_rx_batched+0x83b/0x920 tun_get_user+0x564c/0x6940 drivers/net/tun.c:2002 tun_chr_write_iter+0x3af/0x5d0 drivers/net/tun.c:2048 call_write_iter include/linux/fs.h:1985 [inline] new_sync_write fs/read_write.c:491 [inline] vfs_write+0x8ef/0x15c0 fs/read_write.c:584 ksys_write+0x20f/0x4c0 fs/read_write.c:637 __do_sys_write fs/read_write.c:649 [inline] __se_sys_write fs/read_write.c:646 [inline] __x64_sys_write+0x93/0xd0 fs/read_write.c:646 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd Uninit was created at: slab_post_alloc_hook+0x12f/0xb70 mm/slab.h:767 slab_alloc_node mm/slub.c:3478 [inline] kmem_cache_alloc_node+0x577/0xa80 mm/slub.c:3523 kmalloc_reserve+0x13d/0x4a0 net/core/skbuff.c:559 __alloc_skb+0x318/0x740 net/core/skbuff.c:650 alloc_skb include/linux/skbuff.h:1286 [inline] alloc_skb_with_frags+0xc8/0xbd0 net/core/skbuff.c:6313 sock_alloc_send_pskb+0xa80/0xbf0 net/core/sock.c:2795 tun_alloc_skb drivers/net/tun.c:1531 [inline] tun_get_user+0x23cf/0x6940 drivers/net/tun.c:1846 tun_chr_write_iter+0x3af/0x5d0 drivers/net/tun.c:2048 call_write_iter include/linux/fs.h:1985 [inline] new_sync_write fs/read_write.c:491 [inline] vfs_write+0x8ef/0x15c0 fs/read_write.c:584 ksys_write+0x20f/0x4c0 fs/read_write.c:637 __do_sys_write fs/read_write.c:649 [inline] __se_sys_write fs/read_write.c:646 [inline] __x64_sys_write+0x93/0xd0 fs/read_write.c:646 do_syscall_x64 arch/x86/entry/common.c:50 [inline] do_syscall_64+0x41/0xc0 arch/x86/entry/common.c:80 entry_SYSCALL_64_after_hwframe+0x63/0xcd CPU: 0 PID: 4995 Comm: syz-executor153 Not tainted 6.6.0-rc1-syzkaller-00014-ga747acc0b752 #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 08/04/2023 En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dccp: corrija dccp_v4_err()/dccp_v6_err() nuevamente dh->dccph_x es el noveno byte (desplazamiento 8) en "struct dccp_hdr", no en el "byte 7" como Jann reclamado.
